What Does the Blinking Light on My Furnace Mean?

Jordan is an old Minnesota River valley town on Sand Creek, home to the Mini Met ballpark, and it has added a lot of new housing along US-169 since 2000.
We repair and replace furnaces, air conditioners, heat pumps, boilers and ductless mini-splits in Jordan and across Scott County. Every visit starts with a $79 trip charge and a written price before any work, and the $79 is waived when you go ahead with the repair.
Electricity in Jordan comes from Minnesota Valley Electric Cooperative or Xcel Energy depending on the address.

Book in JordanJordan's downtown sits in the valley where Sand Creek runs toward the Minnesota River, and the older neighborhoods climb the slopes around it. Some of those 1880s–1920s houses sit on sloping lots, with one basement wall at grade and the other buried, which makes for uneven basements: a cold, damp back wall, a warmer front and a furnace set wherever the chimney happened to be. Many also carry a later kitchen or bedroom addition over a crawlspace.
Ramblers and split-levels filled in from the 1950s through the 1980s. Growth picked up after 2000, with subdivisions on higher ground near Highway 169 and Highway 282, built with 90%-plus furnaces venting through PVC and central air as standard. Jordan's population grew by nearly three-quarters between 2000 and 2020, so a large share of homes are now in their first replacement cycle, and finished lower levels in those houses are where most comfort complaints start.
Jordan's valley setting cuts both ways in January. Downtown and along Sand Creek, cold air drains down and pools on still nights, and old houses there with little insulation need all the capacity their furnace has. Up in the newer subdivisions, open ground lets wind pile snow against PVC vents and condensers. Older houses with a furnace and water heater sharing an unlined brick chimney can draft poorly on the coldest mornings, one more reason to keep CO alarms working near every bedroom.
Sand Creek and the Minnesota River bottoms make the low parts of Jordan humid all summer, and basements in the older houses near the creek can stay damp enough to need a dehumidifier. Newer homes on higher ground run into the two-story problem instead: hot upstairs bedrooms and a cool lower level on one thermostat. Cottonwoods along the creek and river shed fluff in June that mats on condenser coils, so a rinse after it stops falling keeps the AC breathing.
CenterPoint Energy supplies gas in town, and its heating rebates cover high-efficiency furnaces, boilers and thermostats with the dealer you choose. Electric programs depend on the address. Minnesota Valley Electric Cooperative ties its air-source and ductless heat pump rebates to enrollment in its off-peak program and requires a Quality Installation contractor for most of them. Xcel Energy customers use Xcel's heat pump and cooling rebates; ask whether the rebate needs a registered contractor. Farms on propane miss the gas-side rebates.
Rebate programs change every year; check the utility's current terms before you buy. Our guides: Xcel and CenterPoint rebates, heat pump rebates, what happened to the federal credits.

It affects the paperwork and possibly your rate. Minnesota Valley Electric Cooperative runs its own rebate programs, separate from Xcel's, and co-ops have offered off-peak or dual-fuel rates for heat pumps paired with a backup heat source. Ask MVEC what's current before you decide, since those programs change the payback. We size the heat pump with a Manual J and help with the co-op's forms.
Sometimes. We check whether the furnace has spare capacity for the added load and whether a duct can reach the new room without starving the rest of the house. Older furnaces are often oversized, so capacity is rarely the issue; the duct path usually is. When a clean run isn't possible, a ductless heat pump head heats and cools the addition on its own.
It can. A furnace or water heater on the damp side sits in higher humidity, which rusts cabinets, burners and vent connectors faster. We check the base, the vent and the burner area for corrosion. Setting the equipment on a raised pad, sealing the return so it doesn't pull basement air, and running a dehumidifier in summer all help. Fixing grading and gutters outside is often the bigger win.
Look from outside for missing mortar, crumbling brick and a missing cap, and have the draft and vent connectors checked at the furnace and water heater. Old brick flues that vent gas appliances can deteriorate from the inside as condensation attacks the mortar, and debris collects at the base. A cleanout inspection and a CO test during the tune-up catch most problems. A liner fixes a flue that's past saving.
